VEHICLE-POLE.

SPECIFICATION forming part of Letters Patent No. 425,847, dated April 15, 1890.

Application filed February 21, 1890. Serial No. 341,375. (No model.)

To aZZ whom it may concern:-

Be it known that I, JOHN ATKINS, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented a new and useful Improvement in Vehicle-Poles, of which the following is'afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

to My invention relates to improvements in vehicle-poles.

The object of my improvement is to rigidly fasten the pole proper to the circle-bar without mortising them together, which of necessity would weaken the circle-bar, by means of a metal clamp, which at the same time inaterially strengthens the circle-bar where it is subjected to greatest strains and gives great stability to the whole. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a perspective of the rear part of the pole embodying my invention. Fig. 2 is a vertical longitudinal section thereof. Fig. 3

2 5 is a perspective of the lower clamping device.

Similarletters refer to similar parts in each view.

My invention consists of the peculiar construction and arrangementof the parts of the 0 clamp, the bolts and the straps, between and by which the pole proper and the circle-bar are rigidly fastened together. The lower piece, Fig. 3, of the clamp is constructed of a single piecc'of metal. The transverse portion 3'5 A is hollowed out or flanged, in which hollow the circle-bar D fits. The longitudinal portion A is )ro'ected alon and under the ole l 1 s P O, being flanged for a short distance 011 each side, in which flanged portion the end of the pole fits, and narrowing as it extends from 40 the flanged portion and curves along the pole, becoming a bracing-strap. The circle-bar D having been placed in the hollow or groove of the transverse portion A and the end of the pole O in the flanged longitudinalportion A, a T-shaped clamp bracing-strap B B, with its transverse portion B on top of the circle-bar and its longitudinal portion 13 on top of the pole,the whole is then firmly bolted together by the bolts F G H I J, substantially as shown in the drawings.

I prefer to extend the longitudinal portion of the T-shaped bracing-strap B B along the top of the pole and bending the end up from the pole, so'as to form the rear portion of the hammer-strap 'E. I prefer to make these parts of malleable iron; but other metals will answer the purpose.

Having described my invention, what I claim, an d desire to secure by Letters Patent, 1s-

The combination of the under clamp-piece, which has the grooved transverse portion to receive the circle bar and the partiallyfianged longitudinal portion to receive the end of the pole, the upper T-shaped clamp and bracing-strap, the pole, the circle-bar, and the hammer-strap formed of a continuation of the upper clamp-piece, substantially as shown and described.
